CREEL-SPOOL-SUPPOBT LOCK.

Application filed. April 4,

each of which the yarn is drawn and passes to a warper or similar machine. In such a creel each spool must be held in a definite fixed position while the creel 1s inoperation so that the yarn may readily be drawn under llllifOlil'l conditions. Fin'therinoro, the sup? port carrying the spindle upon which the spool is mounted desirablyis movable to a second position to enable the spool to be dolled and replaced. The object 0t this inventionis to provide a construction in which the support carrying the spool supporting spindle shell belocked in each oith :e positions so that in the first position the )oolwill be positively hold in operative position endin the second position the support will be positively held in'the positionv required for dofiing. I

lhe object of the invention is further to provide such a construction adapted for each of the large number or; spool supporting spindles with which a creel is provided.

The object of the invention is further to provide such a constructionwhich acts not only to hold the spool supporting spindle in operative position positively and accurately but which also acts to prevent any breakage or dai go to the creel during the dotting operation by holding the spindle positively in dofiing position. I I V These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will claims.

The invention is illustrated in a preferred form as applied to acreel of that typein which the yarn is drawn oil over the end of the spool'or yarn carrier through a guide ber of a creel with which be particularly pointed out in the of; one inein 1928. Serial 9. 267,263.

In the ordinary type of creel. the frame usiiially comprises two convergingside members, each of which supports a large number of spools so that the runs of yarn extend from the outsideof thee-reel to the warper or other machine located at; the front or converging support shown in dofiing posiend of the frame.

comprises a plurality of vertical members Sl'lOWII channel bea ns 1.. But one of these In the construction illustrated, the creel members is illustrated at one side of the frame. These members are assuinedto stand in parallelism throughout the length of each side and afplurality 01. supports are mounted one above the other on each of these members. As each supportis preferably the. same as eve"y other, it is suilicient to illustrate and describe but one. Furthermore, in theprelerred forin of the present invention there is an individual bracket for each spool removably secured to one of these vertical members;

In the preferred embodiment illustrated,

the individual spool supporting brackethasa vertical flange or socket 2 fitting against two faces of the vertical member 1 and re- L-shape device presenting the arm 7 and integral therewith and at right angles thereto the base 8. The spool supporting spindle 9 is mounted in the end of the base 8 oil the support and isa-dapted to carry any suitable for-in; c spool such as the spool. 10. The spool support is pivot-ally mounted. on the This bracket is preferably a single place by a cotter pin 16.

base and for that purpose the end of the arm 7 is shown extending between the base at and the plate 6 of the b 'acket, while a cotter pin 11 forms the pivot securing the support and bracket together.

In the type of creel illustrated, the yarn 12 is drawn oil over the end 01 the spool and passes through a guide eye 13 supported from the creel frame, by means unnecess ry here to illustrate, in alignment with the spindle 9. From this guide eye the yarn passes forwardly to the warper or other machine. It is ditlicult and usually impossible to doll the spool when in tl position by reason of the tension devices, guide eye and other devices on the creel frame and by reason of the yarns running from other spools past or near the spool to be dotted. Accordingly the spool and its support must be moved to a dolling position where the supporting spindle will be in such a position that the spool may readily be dolled and replaced without interference. It is important that the spool support shall be held locked in each of these positions; in the first position to insure that the spool shall be held positively in operative position to deliver the yarn as required in the operation of the creel and in the second position to insure that no breakage, injury or damage be done to the creel or its parts when the spool is removed and replaced from the spindle.

In the present invention a latch is mounted on the spool support and this latch has locking engagement with the bracl'et at either of the two required positions. Such a. latch is shown a lever 14: tulcrumed on one side of the arm 7 of the spool support on a. stud 15 projecting therefrom, the latch being held in This latch is limited in its movement in either direction by lugs 17 projectin laterally from the arm 7. Between one of these l7 and the free end of the latch is mounted a spring 18 which acts normally to swing the nose 19 of the latch toward the base l: of the bracket. 1 he bracket lSPlOVltlQtl in each of the two required positions with a recess 20 and 2l,respectively. In l igr. l the support and the spool are shown in full lines in operative position with the la ch engaging the recess 20, while in Fig. 2 the support'is shown in dotting position with the latch engaging the recess it. in this construction the support and the latch move through a horizontal path with the nose oi the latch ridingovcr the horizontal upper surface of the base 4 of the bracket between the two positions.

Thus the operative has no difliculty in placing the support and the spool in either'ot the required positions. All he has to do is to raise the latch against the spring 18 and push the support one u 1y or the other as required when the nose of the latch will automatically drop into the proper recess. In each position the support with the spindle and the spool are firmly and positively held.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:

1. In a creel for \"varpers and similar machines, a bracket on the creel frame, a sup port pivotally mounted on the bracket and carrving a spool suppertingspindle, and a latch mounted on the support and having lockin engagement with the bracket at either of two positions, in one of which the support is locked with the spindle in operative posi tion to deliver the yarn from a spool thereon required in the operation of the creel and in the other of which the support is locked with the spindle in doll'mg position.

2. in a creel warpers and similar machines, the CO1 itruction defined in claim 1 in which the latch is pivotally mountedon the support to pern'iit its nose to swing toward an d from the bracket, in which a spring between the latch and support acts normally to swing the nose of the latch toward the bracket and in which the bracket is provided in each of said two positions with a recess to receive and hold the nose of the latch in locking engagement.

3. In a creel for warpers and similar ma chines, the construction defined in claim 1 in which that portion 01" the bracket over which the latch moves between the two locking positions extends horizontally and in which the support is pivota ly mounted on the bracket on a vertical axis and carries the latch through a horizontal path.

4-. in a creel tor warpers and similar machines, an individual bracket for each spool, means lor removably securing each bracket to a vertical member oi? the creel frame, a support pivotally moimtedon each bracket and carrying a spool supporting spindle, a latch mounted on each support having locking engagement with the corresponding bracket at either of two positions in one oi which the support is locked, with the spindle in operative position to deliver the yarn from a spool thereon required in the operation oi the creel and in the other of which the support is locked with the spindle in doliing position.

In testimony whereof, I have signed my name to this specification.
